百度智能云服务器BCC使用教程-线上带ofed驱动的实例更换内核方案
概述
线上一些BCC/EBC镜像装有ofed驱动,用户创建带rdma网络功能的套餐的实例后即可直接使用rdma功能。但是ofed是在当前os内核版本下编译的,如果用户改变内核版本后,可能会无法识别具有rdma功能的网卡。这种情况下,就需要重新编译、安装ofed驱动。
本文档提供在不同os的实例上更换内核版本后重新安装ofed的方案。
操作步骤
CentOS 7
以升级内核到kernel-3.10.0-1160.90.1.el7.x86_64为例。
在实例中安装kernel-3.10.0-1160.90.1.el7.x86_64版本内核及相关内核开发包:
yum install -y kernel-3.10.0-1160.90.1.el7.x86_64 kernel-devel-3.10.0-1160.90.1.el7.x86_64 kernel-headers-3.10.0-1160.90.1.el7.x86_64 kernel-tools-3.10.0-1160.90.1.el7.x86_64
有些实例里安装有rdma无损配置包rdma-userspace-config。需要删除该包,等安装好ofed后重新安装:
# 检查是否安装了rdma-userspace-config rpm -qa |grep -i rdma-userspace-config 如果存在就卸载该包 # rpm -e rdma-userspace-config
下载ofed安装包。可以在百度软件源上下载,或者在ofed官网下载后传到实例内:
百度软件源下载,以下载5.8-2.0.3版本ofed为例,在实例内执行下面命令下载
wget http://mirrors.baidubce.com/mlnx-ofed/5.8-2.0.3.0/MLNX_OFED_LINUX-5.8-2.0.3.0-rhel7.9-x86_64.tgz
官网下载,在ofed官网下载对应版本的ofed安装包

编译安装ofed
执行以下脚本,编译、安装ofed驱动。
注意,将脚本和ofed安装包放到同一目录下,脚本中ofed版本和内核版本改为实际使用版本。
整个编译、安装过程要半个小时左右。
#!/usr/bin/env bash # Update mlnx ofed drivers # -- Prepare mlnx ofed drivers # -- Extract and install mlnx_ofed_version=5.8-2.0.3.0 mlnx_ofed_drv=MLNX_OFED_LINUX-${mlnx_ofed_version}-rhel7.9-x86_64.tgz kern_ver=3.10.0-1160.90.1.el7.x86_64 if [ ! -d /lib/modules/${kern_ver}/build ]; then echo "There is no kernel build directory.

wget -q http://mirrors.baidubce.com/baidu/rdma_specs/rdma-userspace-config-v1.0.1-1.el7.centos.x86_64.rpm rpm -ivh rdma-userspace-config-v1.0.1-1.el7.centos.x86_64.rpm service rdma start
重启实例,进入新内核
